Abstract: The mechanochemical reduction of stibnite (Sb₂S₃), copper sulphide (Cu₂S), galena (PbS) and auripigment (As₂S₃) with elemental Fe has been studied. Metallic Sb, Cu and Pb are obtained due to the reducing power of iron. The metal/sulphide nanocomposite particles have been characterised by XRD, SEM and TEM methods. The reduction processes are very straightforward and fast and can be carried out at ambient temperature.
